I use am simple concept:
{{#concept: [[Kategorie:Person]][[Geburtstag::+]]| Alle Personen mit Geburtstag}}
and add a semantic watchlist on it. After that I got a PHP error when I save a page:
PHP Fatal error: Call to undefined function getQueryResult() in /usr/src/extensions/SemanticWatchlist/includes/SWL_Group.php on line 437, referer: http://mysite/index.php?title=Benutzer:Doni101&action=edit
The problem is the result of $result = smwfGetStore()->getQueryResult( $query );
It ist always 0. How can I fix that?
Note: There is a little bug in SemanticWatchlist.hooks.php. $egSWLEnableSelfNotify must be global.
